Ethan, I'm glad you enjoyed my trip report.
I have heard that Lost Valley Trail to Hurricane Deck has fallen into some disrepair. CCC crews have started working on the trail, but they have not yet gotten to the really bad parts. I don't know what the actual conditions are like, however. There are probably landslides. But I really have no idea. Friends of mine went up there but only got as far as the pine tree campsite because that's all they had time for. If you go, send me a report via my web site: santabarbarahikes.com. I can pass it along.
I only hiked Hurricane Deck from Whiteledge in about 1 mile to clear up a spot where people always get lost. After that, prepare to get lost from time-to-time, bring loppers and a saw and be patient. The north-facing slopes of Hurricane Deck did not burn in the Zaca fire so wherever the trail goes behind, it's really overgrown. Last year we hiked from Whiteledge to Potrero. We had hoped the fire had cleared the Deck, but it hadn't and we got torn to shreds in the brush. There's some possibility to stick to the crest, but there are a lot of leftover dead bushes to get tangled in.
The trails are quite obscure since the fire. Volunteers have been flagging and putting up ducks to help you, and there may be human and bear prints to help you, too. It's amazing how the bears remember all the trails. The CCC is making progress, too.
Crossing the Sisquoc (and the Manzana from Schoolhouse back to Nira) will get you wet up to your knees. There is no way to stay dry. We had wet feet all day but stopped hiking in the afternoon and put our shoes and socks out to dry. It's not too bad, though. Just annoying. Someone counted 109 creek crossings on the entire Sisquoc Loop. 34 are between Nira and Schoolhouse. Losing the trail means more creek crossings, too.
Flowers were at their peak when I went, but we've had a little more rain so things are probably holding steady out there. Enjoy it!
